Title: Servocontrol circuit
Inventor: KONO KEIICHI
IPC: G11B5/596
Filed: 1986-09-10
Abstract: PURPOSE:To reduce an overshoot and to shorten a settling time by increasing the gain of a differentiating circuit for position error signal generation from a switching time point by a circuit which performs servocontrol by performing switching from a rough mode wherein a controlled system is driven with a seed error signal to a fine mode wherein the controlled system is driven with a position error signal. CONSTITUTION:An MPU 41 calculates the movement quantity between a current position and a target, a circuit 20 generates reference speed Vc along a speed curve to generate an error DELTAV from actual speed Vr, and a rough contact (a) is selected with a signal MS and amplified to drive a voice coil motor 10 roughly, thereby putting a head 12 closer to the target of a disk 11. When the head comes closer to the target and Vr 0 is detected 40, the point is switched to a fine contact (b) with the signal MS and a timer 41a is started and a positional signal PS is passed through an LPF 30, and integrated 31, amplified 32, and differentiated and the head 12 is driven finely with a sum position error signal  P, thereby positioning the head. The gain of the differentiating circuit 33 is set again by the MPU to the small value with a signal GS after the timer 41a finishes counting a specific time, and the overshoot is reduced to position the head stably in a short time.

Abstract: PURPOSE:To improve the operability and accuracy by covering the external surface except an end surface part with an anticorrosive film, then treating the end surface part of a glass tube with a glass anticorrosive solution and forming a flare part at the end surface part, and grinding the flare part and forming a recessed part. CONSTITUTION:The external surface of the glass tube 2 which has an internal hole where the clad part 3a of an optical fiber is inserted is covered with the anticorrosive solution except the end surface part, the end surface part of the glass tube 2 is treated with the glass anticorrosive solution to form the flare part 2c at the end surface part, and then the flare part 2c is grounded to form the recessed part 2d where the coating part of the optical fiber 3 is fitted. Namely, the flare part 2c is formed in a uniform-angle radial shape, so the recessed part which is concentric with the internal hole of the glass tube 2 is easily formed, and the flare part 2c is formed in the uniform-angle trumpet shape and has a smooth worked surface, so a preferable guide function is displayed. Consequently, the optical fiber clad part is inserted with good operability and the optical fiber coating part is fitted and fixed with high accuracy.

Title: Refrigerator
Inventor: OTA MITSURU
IPC: F25D21/04
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To reduce frosting by providing a water absorption sheet containing a highly water absorbing resin composition on at least a part of an internal wall of a refrigeration chamber and/or a freezing chamber. SOLUTION: Once a door 12 of a freezing chamber 10 is opened to take out foods, etc., in the freezing chamber 10, air containing a more amount of water vapor than cold air existent in the freezing chamber 10 stays around he freezing chamber 10 and a condenser 16. Temperature in the freezing chamber 10 is raised owing to fresh air taken in. Once the condenser 16 enters an operation state following an instruction from temperature control means, water vapor around the condenser 16 becomes a dew point or lower, but since the inside of an internal wall 4 is loaded with a water absorption sheet 2, the water absorbing sheet 2 takes the water vapor to provide dried air so that frost is adhered to the condenser 16 and the water vapor is reduced to change to frost.  A water absorbing resin composition constituting the water absorbing sheet 2 is hydrophilic resin that is insoluble in water and has water absorbing property by at least 20 times the self weight, and reduces its capability as it absorbs a great amount of water.

Title: Failure detection circuit of car control system
Inventor: MATSUDA TOSHIROU
IPC: B60K28/16
Filed: 1983-11-15
Abstract: PURPOSE:To prevent erroneous judgment during the parking brake operation by prohibiting the operation of a failure judgment means outputting a failure signal during the parking brake operation when the relative speed difference of wheel speeds of individual wheel speed systems reaches a predetermined value or more. CONSTITUTION:When the parking operation is performed to perform the parking brake drift turn, a brake is applied to rear wheels. By locking the rear wheels, the detected wheel speed from a wheel speed detection circuit 12b becomes nearly zero, and a comparator 22b outputs an H signal. However, a parking brake switch 28 is turned on, and a transistor 30 is conducting, thus the input of an AND gate 24b is made L. Accordingly, the AND gate 24b is made an inhibit state, and the H output of the comparator 22b is not fed to a failure detection circuit 26b. As a result, even if the wheel speed of the rear wheels is decreased or they are locked by the parking brake operation, a switch 18b is kept on, and the anti-skid control is prevented from being released.

Abstract: PURPOSE:To improve the recognition accuracy by providing a signal recognition means detecting a signal sent from a signal generating means and recognizing a dial number. CONSTITUTION:In a supervimposed waveform C when a prescribed signal is applied during dial rotation, since the circuit of the sending side is opened at an open loop, the impedance is unmatched and the difference from the closed loop is made clear. A line signal appears at a terminal 1, a pulse detection section 3 and a signal generating section 4 are connected to a line section 2 and the pulse detection section 3 and the signal generating section 4 are connected to a control section 5 for control. Thus, the dial pulse detection section 3 and the signal generating section 4 are started at the start of recognition, a prescribe signal waveform superimposed on the dial pulse is utilized to allow the reception side to recognize surely the dial number. Thus, the recognition accuracy is improved.
